Sadly I don't know. I posted pics of it when it came into bloom (so proud, and with much thanks to your advice!). I'm not sure how to link you to it but maybe if you search for my posts you can take a look and see what you think? If I sniff up close I can smell a vague sweet fragrance, but apparently it was striking in the afternoon, and our nanny noticed it too, not just the husband! :-)
